' 1 Application filed October 31, 1908. Serial No. 460,513.

To all whom it may concern:

Be it known that we, Lnwrs A. CARPENTER and RICHARD MIDDLETON, citizensof the United States, and residents of Revere, county of Suffolk, andState of Massachusetts, have invented an Improvement in Pipe-Hangers, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention. relates to a hanger for pipes and like articles and isespecially designed and adapted for use by plumbers, for attaching waterand like pipes to ceilings, walls and like supports.

The present invention has for its object to provide a simple, strong andinexpensive hanger, which is composed of a minimum number of parts andcan be quickly and easily applied 'to the pipe and secured in itsoperative position in a minimum time and with the least possibleinconvenience to the plumber or other operator. To this end, the hangeris composed of a tubular member, which is designed to be secured to theceiling or other support and is provided with substantiallydiametrically opposite slots extended longitudinally of said member, anda movable member comprising a substantially circular body portion toengage the pipe and curved arms extended substantially at right anglesto said body portion, and designed to engage the tubular member referredto, said curved arms having holes for the passage of a screw or bolt,which also passes through the slots in the tubular member and serves tosecure the two members of the hanger together. The screw or bolt may andpreferably will engage screwthreads on the inner surface of the wall ofone of the holes in an arm of the movable member as will be described.These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure l is a side elevation and section of a pipe supported by a hangerembodying this invention- Fig. 2, a cross section on the line 2-2,Fig. 1. Fig. 3, an enlarged section on the line 33, Fig. 2, looking up.Fig. 4, a detail of the movable member. Fig. 5, a detail of thestationary or tubular member, and Fig. 6, a plan of a blank from whichthe tubular member is formed.

Referring to the drawings, or represents the tubular member of thehanger, which are normally separated as represented in Fig. 5, so as toform a tubular member, which is split at one end and is capable of beingcontracted until the lugs or ears 0 are brought into engagement for apurpose as will be described.

The tubular member a, which may be designated the stationary member ofthe hanger is provided with a head f at one end having a hole throughwhich a screw g may be passed, and inserted into the ceiling h or othersupport, said screw also preferably passing through a hole in a washeror bearing plate or disk 2'.

The stationary tubular member a has cooperating with it a pipe engagingmember, which may be designated the movable member of the hanger andwhich is made as shown in Fig. 4, preferably from sheet metal andcomprising a substantially circular body portion m to engage the pipe atand curved arms 0, 79, extended from said body portion I embrace orengage the same on diametrically opposite sides, and said arms areprovided with holes 10, 12, through which a screw or bolt 13 isextended. The hole 10 may and preferably will be provided withscrewthreads 14 to be engaged by the threaded end of the bolt or screw13, and in order to obtain a firm and sufficiently long engagement ofthe threaded end of the bolt with the arm 0, the annular wall 16 of theopening 10 is drawn or bent inwardly as clearly represented in Fig. 3.While we may prefor this construction We do not desire to limit theinvention in this respect, as the threaded end of the bolt may beengaged beyond the arm 0 with a nut (not shown) but in a manner wellunderstood.

In operation with the hanger herein shown, the tubular member aissecured to the ceiling by the screw 1 and the movable member is slippedunder the pipe 11-, after which the arms 0, p, are slipped intoengagement with the tubular member with the holes 10, 12, registeringwith the slots d, after which the bolt 13 is passed through the hole 12and the slots (Z and engaged with the threaded wall of the hole 10. Themovable member with the bolt 13 secured thereto can then be movedlongitudinally with relation to the tubular member at until the pipe hasbeen properly adjusted with relation to the ceiling or support it andwhen so adjusted, the screw or bolt 13 may be set up so as to contractthediameter of the tubular member and effect a firm engagement therewithof the curved arms of the movable member. I

The continuation of the tubular member a may be limited by the walls ofone or both of the slots (5 engaging or biting the screw or bolt 13 orby the'lugs 0 being brought together without the walls of the slotbiting the screw. In either case, the tubular member at such timealthough split has the effect of a solid tubular member having acontinuous circumference and forms a substantially solid supportingmember for the curved arms 0, p of the movable member to grip.'

It will be observed that the hanger herein shown is capable of beingquickly and easily applied as the operator has the free use of bothhands, with one of which he can grasp the pipe and movable member andslip the curved arms of the latter into engagement with the tubularstationary member, and then insert the screw 13 through the hole 12,slots (Z and into the threaded hole 10, after which he can adjust thepipe and movable member on the stationary member with one hand and whenproperly adjusted can set up the screw 13 by a suitable tool in theother hand. It will also be observed that the hanger comprises a minimumnumber of parts, to w1tzthe stationary tubular member, the movablemember and the screw or bolt for clamping said members together, andthat said parts are easily accessible for putting up or taking down thehanger. v

The mpvable member and the pipe can be turned by rotating the stationarymember on the screw g.

Claims:

1. In a hanger of the class described, in combination, a tubular memberprovided with longitudinally extended substantially diametricallyopposite slots, a movable member comprising a curved body portion toengage'the pipe to be supported, and curved arms extended from said bodyportion and engaging said tubular member and having their curvature in adirection substantially at right angles to the curvature of the bodyportion, said arms having bosses provided with holes which register withthe slots in the tubular "member and one of which is provided with ascrew-threaded wall, and a mem screw or bolt extended through the holein one of said arms through said slots and into engagement with thethreaded wall of the other hole substantially as described.

2. In a hanger of the class described, in combination, a tubular memberprovided with substantially diametrically opposite slots having one endwall split to permit said tubular member to be contracted in diameter, amovable member having a body portion to engage the pipe and providedwith arms to engage said tubular member, and means to clamp said arms tosaid tubular member, substantially as described.

3. In a hanger of 'the class described, in combination, a tubular membermade from a sheet metal blank provided at the ends of its opposite sideswith lugs which co operate in the tubular member to form the ,split endwalls of longitudinally extended slots, a movable member provided with asubstantially circular body portion and having' curved arms to engagesaid tubular member, said arms having holes which register with saidslots, and a screw or bolt to clam) the movable member to the tubularleer, substantially as described.
